The film teams the Caped Crusader with both Nightwing (i.e., his former sidekick Robin) and the Joker’s girlfriend Harley Quinn in an effort to stop Poison Ivy from carrying out a diabolical plan to destroy Gotham. Crafted in the style of Batman: The Animated Series, the upcoming feature will be directed by Sam Liu (who also handled last year’s Batman: The Killing Joke), and boast a voice cast including Kevin Conroy, Melissa Rauch, Loren Lester, Paget Brewster, John DiMaggio, and Mindy Sterling.
